"Experts say that migrations from Unix to Linux have slowed down because all the low-hanging fruit has now been picked. Linux growth in the U.S. x86 server market has, over the past six quarters, started to falter and reverse its positive course relative to Windows Server and the market as a whole."More here.

Last month this guy wrote an article describing Open Source and, hence, Linux as a "disruptive" force in the IT market "which will drive prices down and force proprietary software vendors to change their business models". If that happens he won't get paid for writing FUD. Personally, I've spent the last 7 years working pretty much exclusively in Linux and every year I see more job opportunities for my skill set. There have been windows servers at every place I've worked, but they were simply because management forced IT to deal with buggy applications like Exchange. Every time a serious application was considered, windows was not the first choice for the platform. Even at this late date windows is still not ready for prime time. Funny how som many "experts" don't know that.
